具有变压器分接头和补偿动作次数限制的无功优化

针对装有可调变比变压器和补偿电容的电力系统,提出了一种在电力市场模式下进行分段计算的无功优化算法。该方法采用了遗传算法和Alopex方法相结合,能够在满足当日内变压器分接头和补偿电容动作次数约束和电压合格率的条件下,有效地降低网损。通过对IEEE 14节点的计算结果表明,此方法是可行的。

Reactive power optimization with operational limitations of on-load tap changers and shunt capacitors

For the power system equipped with on-load tap changers and shunt capacitors in electricity marke, this paper proposes a sectionalized reactive power optimization method, which combines genetic and Alopex algorithm. This method can reduce the power losses effectively under the condition of the constraints of the maximum allowable number of switching operations and voltage percent of pass. Using Genetic Algorithm integrated with Alopex as the solution method, the computation result of the IEEE-14 node system demonstrates that the proposed method is feasible.
